Social inequality is not good for any nation’s society, no matter how rich it is, like the US. Going down the , leading emerging nations like Brazil and South Africa suffer from high levels of inequality, and if they could significantly clamp down on this, it’s not inconceivable they could make the leap into developed nation power. Inequality can lead to a lot of social ills, and it is literally unhealthy, as a book by 2 British scientists make the case. High crime, high drug use and high rates of heart disease are what societies with high inequality suffer in comparison to those with less. So yes, curbing social inequality should be a bigger priority for many nations than economic growth or flashy, expensive projects.
